ConnectionStrings它们来自哪里?Asp.net

本文关键字：Asp net ConnectionStrings | 更新日期: 2023-09-27 18:06:34

我正在Azure上运行一个带有Azure SQL数据库的Razor站点，但开始收到一条连接错误消息，说它无法连接到App_Data localdb，我不使用它。我还注意到我的项目善意地重新创建了一个localdb，而我在某个时候没有要求它。我已经将Asp标识表迁移到了我的azure sql数据库中，所以一切都很好地放在一个地方(这是个好主意吗？我觉得是这样(。无论如何localdb消息让我很困惑，因为据我所知，我的项目中没有引用localdb。我的web.config有2个连接字符串：

我已经向Kudu检查了这些，这就是网站实际的web.config中的内容，所以没有转换或发布连接字符串。是的，如果我调试azure并查看ConfigurationManager.ConnectionStrings我看到4个连接字符串，而不是2个。最后两个来自我的web.config，第二个为空，第一个读作：

data source=.'SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true}

我不禁想知道这是如何使用的，在哪里使用？

但是，观看ConfigurationManager.ConnecitonStrings[DefaultConnection]是正确的。我的数据库模型初始化如下：

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("DefaultConnection", throwIfV1Schema: false)
    {
    }
    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
    ...

所以这相当平静。值得一提的是，当一切都像这样发展起来时，我正试图启用站点范围的SSL。我已经删除了那个代码，但问题仍然存在：(

以下是关于我看到的错误的更多信息：

更新
我的错误是角色管理器——如果我禁用它，问题就会消失。。。以及角色管理，但仍然！这是一个步骤。。。

ConnectionStrings它们来自哪里?Asp.net

我的问题的答案是，我启用了<roleManager>，认为我指的是ASP。NET Identity 2它们不一样<roleManager>启用了旧版本的身份管理，然后<roleManager>元素默认为localdb。所以这就是额外连接字符串的来源。以下是<roleManager>在Azure的有效machine.config中的外观(注意providers -> connectionStringName(：

<roleManager 
   enabled="false" 
   cacheRolesInCookie="false" 
   cookieName=".ASPXROLES" 
   cookieTimeout="30" 
   cookiePath="/" 
   cookieRequireSSL="false" 
   cookieSlidingExpiration="true" 
   cookieProtection="All" 
   defaultProvider="AspNetSqlRoleProvider" 
   createPersistentCookie="false" 
   maxCachedResults="25">
   <providers>
      <clear />
      <add 
         connectionStringName="LocalSqlServer" 
         applicationName="/" 
         name="AspNetSqlRoleProvider" 
         type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
      <add 
         applicationName="/" 
         name="AspNetWindowsTokenRoleProvider" 
         type="System.Web.Security.WindowsTokenRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
   </providers>
</roleManager>

一旦我发现了这一点，我就更新了我的web.config，指向我的数据库，就像这样：

  <roleManager
      enabled="true"
      cacheRolesInCookie="true"
      defaultProvider="OurSqlRoleProvider"
     >
      <providers>
          <add
             connectionStringName="DefaultConnection"
             applicationName="/"
             name="OurSqlRoleProvider"
             type="System.Web.Security.SqlRoleProvider" />
      </providers>
  </roleManager>

但这只是产生了一个新的错误找不到存储过程'；dbo.aspnet_CheckSchemaVersion'；这是因为角色管理器用于旧形式的asp身份，而不是asp。NET Identity 2。

(这是一个小问题，但我发现这个错误的方式只是简单地通过源代码控制、重建，看看是哪个更改破坏了它。(
